4results about How to "Reduce surface oxidation" patented technology

The utility model discloses a kind of casting magnesium alloy surface treatment equipment, belong to metal surface treatment technical field, its technical scheme main points include rack, the right side of the rack is provided with controller, the inside of the rack is provided with conveying structure, the front side and the back of the top of the rack are provided with preheating structure and drying mechanism respectively, the application is by setting conveying structure and drying mechanism, after conveying structure can realize the continuous conveying of batch in order while carrying workpiece, satisfy batch production demand, the even flow wind scooper in drying frame makes the hot air generated by electric heating disc cylinder evenly blow to workpiece, recovery bucket collects unsaturated hot air, after monitoring filtration by hygrometry filter structure, by suction fan is extracted again and is transported to electric heating disc cylinder to carry out recycling, improve hot air utilization, reduce energy consumption, second temperature sensor real-time monitoring temperature ensures drying stability, solve the existing equipment hot air utilization low, energy consumption is big, the problem of low efficiency.

The utility model relates to an anti -oxidation car stamping part storage frame, including bottom plate, setting at the limiting board of bottom plate four corners, support the support plate of stamping part, limit the position limiting piece of support plate and guide the guide rod of support plate, the four corners of bottom plate all is provided with the guide rod with limiting board, limiting piece sets up on limiting board and limiting piece has along limiting board upper and lower array setting has a plurality, the guide rod is worn in support plate. The connecting structure fixed between the partition and the placing frame body is solved, cannot adjust the placing space height according to the height of different automobile stamping parts, leads to the applicability of placing frame to be poorer, and the use limitation is high, and placing frame can only place a part of the stamping part that conforms to the height, reduces the practicality of placing frame.

The utility model relates to the bus duct technical field, concretely relates to a kind of intensive bus duct, including bus duct main body, vertical plate is vertically arranged between side plate and provides additional support to reduce the deformation caused by vibration, the slot accurately contains copper bar and limits its moving range to ensure that electrical clearance is constant, copper bar as the surface flatness of electric core component carrying large current transmission task needs to be kept to reduce impedance, insulation sleeve tightly wraps copper bar surface and blocks ground leakage current and endures high temperature aging, significantly improve safety performance by multiple protection design, copper bar outer layer is wrapped insulation sleeve to effectively isolate current leakage risk, fireproof filling is closely surrounded slot to form high temperature blocking layer, protective plate and fixed block cooperate to protect internal structure from external force impact, the superposition of anticorrosive coating, fireproof coating and insulating coating is sprayed to realize the triple guarantee of anticorrosion, flame retardant and insulation.

This utility model relates to the field of roll-to-roll calendering technology and discloses a roll-to-roll calendering device for copper alloy heating film. The device includes a segmented heating box, a calendering device on the right side of the segmented heating box, a control panel fixedly installed on the left side of the calendering device, a partitioning mechanism inside the segmented heating box, an adjustment mechanism inside the segmented heating box, and a cover plate on the top of the segmented heating box. The segmented heating box and the cover plate are fixedly installed by bolts. The device releases cold rolling stress in stages through gradient annealing (200℃→120℃→50℃), significantly reducing the risk of bending cracking, eliminating the need for offline annealing, improving production efficiency, and eliminating the need to re-roll the cold-rolled copper foil roll, saving time and effort, and avoiding the probability of damage to the copper foil from multiple windings, thereby increasing the yield.
